Abstract

A servo drive system of a press machine uses servo motors (30a,30b) as driving sources of a ram. The servo motors (30a,30b) are opposed to each other at opposite ends of an operation shaft which vertically moves a ram (22), and the servo motors (30a,30b) composite and use torques based on the same speed-torque characteristics. Necessary ram pressure can be generated without utilizing inertia of a mechanism, and the system employs a pair of servo motors (30a,30b) in which if a load is received from a work during a lowering operation of the ram (22), motor speed is reduced according to the load, thereby reducing the lowering speed of the ram (22). The pair of servo motors (30a,30b) are integrally operated, thereby directly driving the operation shaft.
